Its dialogue doesn't appear in the conversation. Instead, the previous node is being repeated for some reason, then this one is automatically skipped.
Other dialogue nodes earlier in the conversation work fine with the continue button there. It's just this one node it seems to have an issue with.
I've tried changing its dialogue, made sure it's not connected to any events, tried deleting it and redoing it, and disabled the Unity UI Typewriter Effect temporarily just to rule that out as the problem, but it's still behaving the same.
When I don't include the continue button and let the dialogue finish own its own, it seems to work smoothly. Problem is, I need the continue button.

I figure I'm doing something wrong as I'm very new to this system (only started last week and still working my way through learning the documentation).
